Title: Rubber-styrene graft polymers and their production
IPC: C08F279/02
Filed: 1965-11-09
Abstract: A rubber-vinyl aromatic compound graft polymer is produced by partially polymerizing a mixture of a vinyl aromatic monomer and rubber in bulk until substantially all of the rubber precipitates from the monomer to produce a prepolymer and subsequently adding said prepolymer to an aqueous suspension system in which a water-insoluble phosphate salt is utilized as the sole suspending agent, addition of said prepolymer to the aqueous suspension being commenced substantially immediately at the start of the addition of said phosphate and the addition of the prepolymer and phosphate being continued gradually in a manner such that the prepolymer will remain at all times in stable suspension and effecting further polymerization of the prepolymer in said suspension until substantially complete polymerization is obtained.  In a modification of the process, part of the phosphate is present in the suspension prior to addition of the prepolymer, the remainder being added concurrently with the prepolymer.  Specified phosphates are calcium, barium and magnesium phosphates. In the examples, styrene-butadiene rubbers are grafted with styrene, using tricalcium phosphate as suspending agent.

Title: Organic polymeric salts and lubricating oil compostitions containing such salts
IPC: C07D207/412
Filed: 1963-12-17
Abstract: Lubricating oils include, as an additive providing stability, anti-sludge, wear-inhibiting, corrosion-inhibiting and detergent properties a minor proportion of a sulphonic acid salt of a succinimide base of the formula <FORM:1055429/C4-C5/1> wherein R is a C20- 500 polymerized alkylene or arylalkylene group and X is the residue, after the removal of a primary amino group, of an alkylene or arylene polyamine containing at least one primary amino group.  In a modification, the additive may comprise a mixture of the salt together with the parent succinimide base.  The sulphonic acid component of the salt may be aryl, alkylaryl or alkyl sulphonic acid or a sulphonation product of petroleum or aromatic extracts from lubricating oil or kerosene.  The lubricating oil used may be a mineral oil, e.g. that obtained from a paraffinic and/or naphthenic crude, optionally blended with fatty oils and/or synthetic lubricating oils.  The latter (unspecified) may be used as the sole lubricating oil.  Other ingredients may also be included, e.g. alkylphenols, arylamines, dialkyl sulphides, phosphite, phosphate and phosphonate esters and salts and their thio-derivatives, P2S5-terpene reaction products and alkali metal salts thereof.ALSO:Oil soluble compounds suitable as lubricant additives comprise salts of an organic sulphonic acid and a succinimide of the general formula <FORM:1055429/C3/1> wherein R is a C20- 500 polymerized alkylene or arylalkylene group and X is the residue, after the removal of a primary amino group, of an alkylene or arylene polyamine containing at least one primary amino group.  The basic component of the salt may be prepared by heating maleic anhydride with a polymer or copolymer of an alkylene and/or arylalkylene, e.g. polypropylene, polybutene, ethylene-isobutylene copolymer or ethylene-a -methylstyrene copolymer, so as to mono-alkylate the anhydride, and heating the substituted succinic anhydride so obtained with an appropriate polyamine, of which many examples are given, the preferred ones being tetraethylenepentamine, diethylamino-propylamine and dimethylamino-propylamine. The polymer base is then converted to the sulphonate salt form, for example by adding a sulphonic acid to a solution or suspension of the base in a suitable liquid medium or by adding the acid to a melt of the polymer base; not all the base need be neutralized by the sulphonic acid, for example only 10 to 50% by weight of the mixture need be in salt form.  Sulphonic acids exemplified are benzene-, alkylbenzene-, naphthalene-, alkylnaphthalene-, naphthol-, alkyl-sulphonic acids and the sulphonation products of petroleum fractions and aromatic extracts from lubricating oil fractions or kerosene.

Abstract: 1370816 Load gripping devices GROUPEMENT POUR LES ACTIVITES ATOMIQUES ETAVANCEES 28 Oct 1971 [29 October 1970] 50278/71 Heading B8H A device for gripping long cylindrical objects consists of a framework 1 provided at least at each end with a bi-stable gripper including jaws 2, 3 which are mounted on a pivot 4 and which are connected by links 6, 8 to a toggle linkage 11, 12. The pivot 9 connecting the links 6, 8, 11 is constrained to move vertically, and the pivot 13 connecting the toggle links 11, 12 is mounted in a transversely movable slide member 14. The toggle link 12 is telescopic and is connected to the frame work by a pivot 15. Transverse movement of the slide member 14 to open or close the jaws 2, 3 at a predetermined location is caused by the action of fixed jacks 32, 33. As shown, actuation of the jack 32 will cause opening of the jaws- Initial movement of the jack piston causes a piston 27 to move to the end of a bore in the slide member 14 against the action of a spring 31, thereby allowing balls 25 in openings in the member 14 to be released from locking engagement with grooves 23 in the wall of the hollow cylindrical member 22 housing the slide member. Continued movement of the jack piston then moves the slide member to the left until it engages a stop member 19<SP>1</SP>, thereby moving the pivot 13 through the dead-centre position between the pivots 9, 15. Similarly, actuation of the jack 33 causes closing of the jaws. Supplementary jaw pieces 36 may be provided for gripping objects of different diameters.

Abstract: 1326640 A tool for connecting and disconnecting electrical components BURNDY CORP 23 Oct 1970 [24 Oct 1969] 50391/70 Heading B4C [Also in Division H2] A tool for attaching an elbow terminal 15 to, or removing such a terminal from, a transformer bushing 16 comprises a casing 10, an elongate tubular member F movable longitudinally relative to the casing between two limit positions by means of a compression spring mechanism, a rod 28 carrying two jaws 24 adapted to engage an opening 25 in a projection 23 of the elbow, means for moving the rod and jaws longitudinally relative to the tubular member F to cause closing and opening of the jaws, detent means for locking the tubular member in each of said two positions, and a trigger arrangement for releasing the detent means. The means for moving the rod longitudinally relative to the tubular member F includes a hand grip 14 which is rotatable relative to the casing 10. A sleeve 40 connected to the hand grip has a longitudinal slot 41 for receiving a pin 42 secured in a block 43 rotatably mounted on the rod 28. The pin 42 extends through a helical slot 47 in the tubular member F so that upon rotation of the hand grip, and as the member F is non-rotatable relative to its axis, the rod 28 will be moved longitudinally relative to the member F. The jaws 24, which are pivoted at 26, in the open condition extend through slots 30 in the member F, and, upon longitudinal movement of the rod 28 to the right (Fig. 8), edges 32 cam the jaws to their closed position. In use the part 20 of the casing 10 which is transparent is positioned over an elbow terminal attached to a transformer and the hand grip 14 is rotated to engage the jaws in the opening 25. The tubular member F is locked against movement relative to the casing away from the transformer by detent means which includes a sleeve 79 biased by a spring 80 to the position illustrated in which balls 76 are locked against radial outward movement. Movement of the lever 87 to the position illustrated in Fig. 4 moves ring 63 away from shoulder 60. Actuation of trigger 13 releases the detent means and results in rapid movement of the tubular member F and the rod 28 to the right. The elbow terminal is thus removed from the transformer, and the tubular member F is moved to the position of Fig. 5 in which, upon release of trigger 12, it is locked against movement to the left. For attaching an elbow terminal to a transformer the tool is operated similarly excepting that the tubular member is positioned as in Fig. 5 and the lever 87 is moved to a position (Fig. 6, not shown) in which the ring 64 is moved to the left and away from shoulder 61. Actuation of the trigger 13 will then permit the member F and the rod 28 to move to the left relative to the casing to effect the attachment.

Abstract: 1440507 Photographic printers XEROX CORP 2 Nov 1973 [3 Nov 1972] 50979/73 Heading B6W In a printer wherein images of characters on a continuously rotating matrix drum 60 are projected by a lens system 92 onto a continuously moving photoconductive surface 20, the lens system is arranged to be movable so that the first line of characters formed on the drum 20 may always be at a predetermined location even if there is a delay in printing the line due to drum 60 not being in the required position. As shown the drum 60 carries a band 70 of characters for each character position in a line, thecharacters in a band being repeated in each of six drum segments 73. A series of flash lamps 81 and a prism arrangement 87 enables instantaneous illumination of a required character as it passes across a lens system 92. After a "start-print" signal is sensed by the apparatus the surface 20 starts to move but the character drum is not ready until it has rotated to a starting position (as determined by the sensing of index mark 78). To compensate for the movement of surface 20 during this time the lens system is moved tangentially to the surface of the character drum in a series of steps corresponding in number to the number of segments 73 separating the instantaneous position of the character drum from its starting position. A movable mask 95 supported on the lens system holder moves with the lens system to define the area of surface 20 which is exposed. The image of a pre-printed form may be superimposed in the selectively printed matter and the images developed, transferred to a final support and fixed in a conventional manner (Fig. 1, not shown).
